Optical fiber switching device and method.

摘要

There is disclosed an optical fiber switching device having a coupling board (1) comprising a plurality of first optical fibers (3) connected to one surface of the coupling board in the arrangement to one surface of the coupling board, a plurality of second optical fibers (6) connected to the another surface of the coupling board, an optical fiber length adjusting unit (9) for handling surplus portions of the second optical fibers (6) and switching unit (13) for pulling out any one of the second optical fibers (6) selected from the plural second optical fibers from the another surface of the connecting board and for connecting the any one optical fiber to different switching position of the another surface of the connecting board to coupling the any one optical fiber with any one of the first optical fibers. <IMAGE>
